I've never yet seen one where this really is the case. CRT's just seem to
be inherently non-linear in the

Sorry to be difficult, but I don't believe that this is correct, and this
is exactly what I would like some confirmation of - either way. The whole
point of the non-linear transformations or mapping that leads to the
'gamma' that we are discussing is to make equal digital brightness steps
Julian, I'm surprised no-one has given you a decent answer yet. I'm going to
launch-in, risking life and limb as a newbie to this list...
I believe that by creating a JPEG of your wedge and embedding within it a
reference to the sRGB profile, you have told Internet Explorer to translate
the
Not to be funny; but how sure are you fo the acccurracy of your step wedge?
Most commercial step wedges are created using precision measurement
instruments and printed to precisely measurable standards. Is it possible
that you personnally created step wedge may be out of gamut at the dark end

I followed the Photoscienta page http://www.photoscientia.co.uk/Gamma.htm ,
and successfully set up my gamma - I selected a gamma of 2.0. Checked it
at two other sites with good test patterns (Timo's gamma =
I did nto read the post thoroughly; but I would suggest that some of the
difference may very well be that your monitor is set at a different color
tempurature than those that you looked at which would effect the rendering
of the gamma setting. Moreover, you may not have hour monitor's brightness
